I downloaded the virtual file for Ubuntu server. I've read through the online instructions and they mention they are not all encompassing. The problem is the only Unix/Linux I have played with is the GUI version like Ubuntu desktop. The instructions point to the files that need to be edited, but I just don't know the commands and Google hasn't been much help.

Anyone have step-by-step commands I can use to get this running. I'm testing only now. I just want to make the basic edits, add a few users, etc. I can get to the default web page, but no users setup so I can't really test.

For starters, make sure you have the latest ZendTo installed (I changed the way mail sending works a bit a few versions ago). If you have Postfix installed, then look in /etc/postfix/main.cf and setup your SmartHost setting (the SMTP mail server you send all your mail to). Then restart Postfix (sudo service postfix restart) and it should start to work.

Thanks for the reply Jules. It turns out it's not ZendTo that's causing the mail issue. I can send test messages from postfix all day if I do it by IP so it's just a DNS issue I haven't sussed out yet.
